Friggin' Laser Beams, High Speed Data Transfer
Interesting article
Right now, workers are installing lasers atop tall office and residential buildings in New Jersey to link two NYSE data centres, spread 35 miles apart. Other companies plan to install similar networks.
Comments
Will it still functional if someone decides to build a high building/tower in between those data centers?
I highly doubt that
although it would be easy to hijack data with a helicopter a mirror and a receiver!
Suddenly A Wild Amazon Prime Air Drone appears!
What is this bullshit?
The picture is photoshopped because you normally can't see a laser, only reflection disortion such as dust.
It's not faster than fiber optics because it's both light, and as others said in comments too, it would be incredible easy to mess with.
Unless I'm missing something I don't see how it would persist in bad weather as they claim, if they use high frequencies to solve this problem then you might aswell call it "aimed radiowaves".
Sounds like either a hoax or some silly hype to overcharge wall street monkies with who never paid attention at physics or chemistry...
The slightly shorter distance the light has to travel compared to it being in an optical fibre curving around could reduce the latency, but probably not by any noticeable amount
Frequencies higher than the light used in the typical laser, likely infra-red or visible, would be in the ultraviolet range, not radio.
light speed in fiber is slower than in air.
You're right, not a total expert at these things but my standpoint remains.
Light speed on earth is always as fast, especially considering it doesn't even go through a material, at best bounces at the sides of the fiber cable.
I hope they will actually manage to sell those and get reports for either light vandalism (flashing data at night time, err) or reports of birds having cancer...
google "refractive index". also speed of light in vacuum on earth is slower than in space.
it will be save lot money.. i imagine if i have a dedicated server that have ability like that..
Actually, the area where light travels in a fibre is glass, around a refractive index of 1.6 according to wikipedia. That means light in a optical fibre travels at around 60% (1/1.6) of the speed it does in a vacuum, compared to air with a refractive index of around 1.0003.
Note: Refractive index refers to the phase velocity, not the group velocity (which is what actually transmits information), but they're usually closely related for most materials.
This idea has been around forever (both with lasers and LEDs) in the meshnet communities , and the problem has always been obstruction of the beam - either through buildings, or through for example fog.
Moon hosting incoming!
How about they run the lasers under ground? less likely hood of getting blocked
Unless there is structural support of the tunnels, earthquakes.
